Waypoint not Unlocking Achievements

I’m nowhere near being a hardcore Halo Gamer. I enjoy the games in mainly single player, play co-op from time to time, never multiplayer. My wife picked up Anniversary as a Christmas gift for me and I sat down to play it.

I completed a couple of achievements and unlocked 3 achievements worth 45 GS. However, Waypoint shows them as still locked. I’m confused as to why that is. Would anyone plese explain this? Thanks.

im having a similar problem to this. most of my achievements are not showing up. this website is terribly crippled and they really need to fix it…

forum ranks

custom challenges

and now this?

have you looked on ur console

None of my achievements show as unlocked in Waypoint either. My GT does show them however.
